To a-ZZ whom it may concern: y

Be it known that I, MARIO SCHIESARI, a subject of the King of Italy, residing in Turin, Italy, have invented certain new and useful Improvements in Type-IVriting Machines, of which the following is a speciiication.

This invention relates to the general class of writing machines which are operated by the fingers and hence called dactylographie, and the object of the invention is to provide a writing machine of this general character of a simple and comparatively inexpensivey nature and of a convenient and compact construction, having novel and improved means capable of operation whereby words or syllables `up to six letters may be written simultaneously de. pressing the corresponding keys thereby enabling the writer to operate about four times as fast as with ordinary typewriting machines and to take down the speech or dictation of the most rapid speakers.

This invention also consists in certain novel features of the construction and com-v binations and arrangements of the several parts of vtheimproved typewriting machine. whereby certain important advantages are attained, and the device is rendered simpler, less expensive, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims.

In order that my improvements may be the better understood, I will now proceed todescribe the same with reference to the accompanying drawings, wherein- A l y igure 1 is a plan view of a machineconstructed in accordance with my invention, the upper vpart of the carriage being omitte Fig. 2 is a vertical sectionon the line -m of Fig. l; Fig. 3 is a rear elevation of the device disclosed 5` and Fig. 4 is' a' detail view'o Vthe rear or back part of the machine illustrating the disposition and operation of the spacers.l View of the winding key employed, in connection with the embodiment of the invention disclosed. f

carried by a key lever 4, fulcrumed at' 5.,) said key lever transmitting its movements t5'. a second or intermediate .lever-.7 through a Fig. 5 is a detail. h

(see Fig. 4) consists o lReferring to Figs'. 1 and 2, each key 1 ie coupling link 6. The .lever 7 is ulcrumed at 8 and moves up' yand down, While its ful,- crum is mounted in upright pivots 11 in a bar 10 so that the lever ma swing laterally. The second levers 7 aren coupled by links 12 to the respective type-.levers or hammers 13, and also by links spacers 15. When a key 1 isdepressed it acts through'the parts described to operate the type bar-13 to cause the type carried thereby to strike thepaper and effect the printing impression and .operates also the link 14 which controls the spacer 15, which, as will be seen-lated herein, has for its obleIt to right. On removing the pressure of the linger `from the key, aspring 17 aided by an auxiliary spring 104 (see Fig. 3). re-

)ectto displace thasuspension bars 16 from tracts t-he .parts to theirfnormal position. I

The depression of each key also sets in m0- tion the carriage and the ink ribbon'. If a key, and through it the type-lever which it controls, bears three characters there is .added to the keyboard a key which controls the commutator, theobject of which 'is to shift the character or .letter desired into proper position with respect to the line being written.y l

Each t, p e bar 13 (see Figs. '2 and 3) is fulcrumed on a pivot 24 carried by an arm .20 on a suspension` bar 16, suspended from the upper part 19 of the ame by screws 18, in such a manner that -it may oscillate laterally. Each suspension bar 16 carries at its lower part (see Fig. 4) a spacer 151 and, a

small roller 21, on which bears the spacer of the adjacent bar, and it is provided below witha little sphere or ball 22 (see Fig. 2) which bears against`the sides of 'a' U- shaped guide 23, sofas to render more easy the lateral movement or suspension bar 16 itself.

displacementofV the The bar 13 controlled by 'the lreyli'with which it is connected carries at its free end v the types, and is also provided at its extreme end with a pin 25 which, when. the ammer descends, engages, a slot or groove in the final guide 101 for assuring alinementl The spacer 15 of characters in writin a small campiv- {oted on the suspension bar 16 and disposed bear against the small roller 21 on the Ildjacent ar as stated.1 fOn depressing a key, and consequently the intermediate lever 7, the spacer link14 is drawn down and this rocks the spacer cam 15 in such a inanner as to cause it to act on the adjacent roller 21 and move laterally the suspension bar 16 on which said roller is mounted. As is believed to be obvious this will displace all of the bars successive to that which has been displaced by the key, as before stated. In the case, where for example, three Akeys have been depressed at the same time, the several displacements will be added together or combined in such a manner that the last letter printed Will be displaced three times the usual letter space.

The movements of the carriage With the .paper Should, obviously, be proportional to the number of keys depressed. The povver required for moving the carriage is supplied by a spring inclosed Within a casing or drum 52 (see Fig. 3) Which may be tensioned through the turning oi the arbor 56, which acts to Wind the spring through bevel Wheels 54 and 55 and which is rotated either by means' of va key 58 or by means of a pedal acting through a cord Wound about a-drum 57 mounted on ,the arbor 56. The drum 52 (see Fig. 2) is integral with a gear Wheel 53 which gears with the second Wheel 59 secured to an arbor 60 and this arbor transmits the motion to an upper Wheel 61 which latter communicates.' its movement to the carriage.

In order to render the movement of the carriage proportional at all times to the number of type keys that may be simultaneously pressed, there is a mechanism comprising a detent 43 fixed against lateral play, which also prevents the rack and carriage from displacement and a special detent 44 which allows a lateral displacement equal to thev sum of all the dis lacements caused by the spacers. The disp acement of the last suspension bar 16 is communicated to the special detent 44 through levers 50 and 51 against which a spring 49 presses the said detent 44. W hen the pressure is removed from the type keys, the detent 43 is disengaged from the rack the moment after the special detent 44 .is enga-ged therewith. Then the rack, with the carriage, following the rotation of the upper Wheel 61 is dis-v placed laterally to an extent up to that when the special detent 44 shall reach its position ofrepose, this -detent being capable of movement in a horizontal plane only. The return of the carriage may be automatically controlled. by a s ecial mechanism and as is believedto he oovious, and the machine is provided rvith any ink ribbon feeding device. lt is also thought/to be Well to mention that in a machine othis character it is necessary that the carriage and the key board be disposed in such a mr nner as will permit of "Writing any syllable in going from left to right fr lout having to return or go back.

It the characters are distributed over the key board in rovvs or lines, all the characters required must be found in the same line.

The disposition oit the letters and other characters on the key board may be more or less modified according to the phonetic peculiarities of the particular language, each letter or character occupying a position, such as will permit all of the combinations in which they enter in the composition of any syllable. In general, in considering that in all languages there are syllables consisting of a vowel preceded or followed by one or more consonants, we conclude at once that it is advantageous to place the vowels in the central part of the key board and the consonants in the lateral parts of the same.

Suppose We Wish to Write any Word, for example encre AWe first Write the syln lable en by depressing the keys bearing these letters; Then the 'key lever 4 (ses Figs. 1 and 2) commanded by the key a through the intermediate lever 7 draws down its link 12 Which causes the type bar to strike the paper at the central part of the impression at the same time that the intermediate lever 7 draws down the spacer link 14 (see Fig. 4), thus operating the spacer 15 Which displaces the Whole system ot suspension bars 16 toward the right, in such a mann ner that the bar bearing the letter n also actuated Will ystrike the paper and print the letter n thereon a letter space to the right. of the center of the impression. The suspension bar 16 which carries .the letter n also displaces the suspension barsat its right to the same extent and in consequence, the last suspension bar 16 will be displaced two letter spaces. This displacement is C0mmunicated by the bar 50 to the special detent 44, disengaged from the outer rack on the' bar-45 tsee Fig. 1) by the action oft-he lili los

intermediate lever Z on the bar 47 and the detent'operating arm 42. When pressure on the keys is removed, 'the springs, hereinbefore referred to, bring all the parte to their' normal or initial position, the special datent 44 engaging the rack tvvo teeth farther to the right than before and accompanying the .movement of the carriage up to the position iis l 25 bars, movable` relatively to the dp depi essionof the keys for moving said suspension .bars latera 1y for spacing, means assuring alinement, a carriage for the paper and means for -variably moving said car.- 5 riage proportionately to the spacing.
